INSTALLING RAIL SYSTEM PARTS
MOUNTING COVER AND DISCHARGE ELBOW
Mounting Hatch Cover, Discharge Elbow, Discharge
Pipe and Rails–Use the following steps.
1. Set concrete cover with hatch opening in
position. If basin cover is to be steel or aluminum,
secure the cover to basin walls with expansion
bolts, see Fig. 6.
2. Bolt rail guide plates to frame as shown in Fig. 6.
Guide plate Fig’s. 8 and 9. Stainless steel bolts
are screwed through frame angles when shipped
and nuts are provided to hold the plate. Brackets
have vertical slots so that it can be adjusted for
final fit on rails and horizontal slots to allow for
side movement. Plate for 6" lift-out has longer
slot so plates can be moved to obtain 28" center
between plates. See drawing, Fig’s. 6, 8 and 9.
3. Drop a plumb line from center of tapered rail
fitting casting to basin bottom. Mark these
points on the concrete. IMPORTANT – Concrete
bottom must be level and smooth for mounting
discharge.
4. Set discharge elbow casting so that centers of
rail guide holes are centered on marks from the
plumb line.
5. With casting properly aligned, mark positions
of hold-down bolts. Remove casting and drill
concrete bottom for expansion bolts. Use 3/4"
bolts 2-1/2" long.
6. Set discharge elbow casting in place and secure
with bolts.
7. Recheck with plumb line to be sure rail alignment
will be correct.
8. Now install discharge pipe to height required.
NOTE – Discharge elbow flange is tapped so cap
screws must be used on lower flange. Use
(5/8"-11) x 2-1/4" long cap screws for 4" flange
and (3/4 x 10") x 2-1/4" long cap screw for
6" flange. Discharge pipe can be schedule
40 galvanized steel, schedule 80 plastic pipe
or ductile iron pipe.
9. Cut rail pipes. All installations must use rail guide
bracket. This guide bracket is furnished in the lift-
out rail package. Figure 7 If basin depth is more
than 25 feet deep, a second guide bracket must
be used. This second bracket must be ordered
separately if required.
10. Lower rail guide pipes are cut 5 to 6 feet long,
and both must be exactly the same length. Rail
pipes are schedule 40 galvanized or schedule
40 stainless steel and 1-1/2" size for 4" pump
systems and 2" for 6" pump systems.
11. Set the lower rail support bracket in position
with tapered guides into lower pipes. Put U-bolt
around pipe and tighten lightly. Align pipe plumb
and tighten U-bolt nuts. Tighten set screw in
base casting against rails.
12. Measure from joint on tapered plug on lower
support bracket to joint of tapered plug on top
holding plate and cut two rails to this length. Put
rails in place and tighten screws in upper guide
plate. Holes in plate are slotted to adjust for any
error in rail pipe length.
13. Recheck rails; they must be plumb and straight.
Move lower guide bracket if necessary to
perfectly align rails. Upper guide plate can also
be moved 1/2" either way horizontally.
14. If basin depth is more than 25 feet deep, two
guide brackets must be used. Set the second
bracket 10 to 15 feet above lower bracket or at
less height if discharge pipe is shorter. 21 feet of
rail pipe can be used above top bracket.
15. IMPORTANT – If one size larger discharge pipe
is required, such as 6" pipe on 4" lift-out system
and 8" pipe on 6" lift-out systems, an eccentric
flanged reducer must be used on the discharge
elbow. Also, a special U-bolt must be used in the
lower support bracket. This larger U-bolt must
be ordered separately. The support plate is also
drilled for the larger U-bolt. See Fig.7.
16. If not possible to use hatch cover, a special rail
bracket can be furnished for mounting directly to
basin wall with yoke assembly. This bracket is set
and aligned with discharge elbow the same as
described for rail mounting plate on cover frame,
which is to set yoke first, then drop plumb line to
align discharge elbow in bottom of basin.
MOUNTING CHECK VALVE OR STRAIGHT
FLOW THROUGH FITTING TO PUMP
The check valve face or through flow fitting also
acts as the sealing flange. An O-ring is used in the
face for leak-tight seal. Be sure O-ring is properly in
groove and not cut or nicked. All bolts and gaskets
are supplied with valve. Use following steps to mount
valve and aligning plate. See Fig. 2.
1. Bolt check valve to pump discharge flange.
2. Install galvanized pipe guide into check
valve socket. Secure set screw, but do not
tighten tight.
3. Install guide plate over pipe and connect plate
arm to top of pump. Remove bolt in pump and
replace with longer bolt furnished to hold plate
arm in position. See Fig. 2.
4. Remove adjusting bar and tighten set screw into
guide pipe.
5. Check all parts to be sure guide pipe is vertical
in line with pump. Loosen bolts in check valve
flange to move valve if necessary for alignment.
Play in the bolt holes allows for some alignment.
6. Now tighten all bolts and set screws and reinstall
adjusting bar.
7. Set adjusting bar so that there is a gap of about
1/4" between bar and guide plate. See Fig. 2.
